what is wrong with this code? why does it return a negative value (if I use a lower number like

20

it seems to work, but a number like

100

will also cause a large negative value )

println(fibonacci(50).last())

fun fibonacci() = generateSequence(Pair(0, 1), { Pair(it.second, it.first + it.second) }).map { it.first }

fun fibonacci(n: Int): Sequence<Int> = fibonacci().take(n)
